Creating developer memberships
The process for signing up for a developer membership in either store is different. Since the prerequisites and steps to do so may change at any given time, I will spare you the step-by-step details.
Enrolling in the Apple Developer Program
To sign up for an Apple Developer account, point your browser to https://developer.apple.com.
Joining the Apple Developer Program requires an Apple ID. As of the publishing of this book, members pay a $99 annual fee for the program.
Signing up for a Google Play Publisher account
To get started with your Publisher account, point your browser to https://play.google.com/apps/publish.
To sign up for a Google Play Publisher Account, you will need a Google Account-usually, this is your Gmail address. As of the publishing of this book, the program requires a $25 one-time fee to join.
